IETF BMWG Work Items 63rd IETF Meeting – Paris, France Tuesday 8/2/05 1 Work Items 1. NETWORK LAYER TRAFFIC CONTROL MECHANISMS (WG Last Call) 2. IGP DATA PLANE CONVERGENCE (WG Last Call) 3. ACCELERATED STRESS TEST (BMWG Work Item) 4. NETWORK PROTECTION MECHANISMS (Proposed WG Work Item) 2 NETWORK LAYER TRAFFIC CONTROL MECHANISMS (WGLC) • Co-authors are Scott Poretsky of Reef Point, Jerry Perser, Shobha Erramilli of Qnetworx, and Sumit Khurana of Telcordia • draft-ietf-bmwg-dsmterm-11.txt, Terminology for Benchmarking Network Layer Traffic Control Mechanisms – WGLC was successfully completed for this document – Final action item was to resolve I-D Nits. This was completed in the –11 submission. – Ready for IESG? • draft-ietf-bmwg-dsm-meth-00.txt, Methodology for Benchmarking Network Layer Traffic Control Mechanisms – Will be submitted prior to IETF 64 – Anyone interested in being a co-author? 3 IGP DATA PLANE ROUTE CONVERGENCE (WG Last Call) • Co-authors are Scott Poretsky of Reef Point and Brent Imhoff • 3 documents completed WGLC 1. draft-ietf-bmwg-igp-dataplane-conv-app-07.txt, Considerations for Benchmarking IGP Data Plane Route Convergence 2. draft-ietf-bmwg-igp-dataplane-conv-term-07.txt, Terminology for Benchmarking IGP Data Plane Route Convergence 3. draft-ietf-bmwg-igp-dataplane-conv-meth-07.txt, Benchmarking Methodology for IGP Data Plane Route Convergence • 2 more changes required: 1. LC review identified inconsistency in Methodology and Terminology • • -07 Methodology uses "throughput" and refers to RFCs 1242 and 2544. –07 Terminology uses "forwarding rate" and makes no reference to RFC. Action is to keep the Methodology as-is and in the –08 Terminology replace occurrences for "forwarding rate" with "throughput" and reference RFCs 1242 and 2544. 2. Need to resolve I-D Nits • Given these two changes, Ready for IESG? 4 ACCELERATED STRESS (BMWG Work Item) • Co-authors are Scott Poretsky of Reef Point and Shankar Rao of Qwest • draft-ietf-bmwg-acc-bench-term-06.txt, Terminology for Accelerated Stress Benchmarking – Ready for WGLC? At recommendation of BWMG co-chairs, Methodology divided into separate documents: – draft-ietf-bmwg-acc-bench-meth-03.txt, Methodology Guidelines for Accelerated Stress Benchmarking • • Ready for WGLC? – draft-ietf-bmwg-acc-bench-meth-ebgp-00.txt, Methodology for Benchmarking Accelerated Stress with Operational EBGP Instabilities – draft-ietf-bmwg-acc-bench-meth-opsec-00.txt, Methodology for Benchmarking Accelerated Stress with Operational Security • Input provided by OpSec WG – Advantage of this format: additional technology specific methodologies could be added 5 • NETWORK PROTECTION MECHANISMS (Proposed WG Work Item) (1 of 2) Co-authors are Scott Poretsky of Reef Point, Jean-Louis LeRoux of France Telecom, Takumi Kimura of NTT, Shankar Rao of Qwest, and Rajiv Papneja of Isocore • • draft-poretsky-protection-term-00.txt, Benchmarking Terminology for Protection Performance – At request of co-chairs, this work item provides a single Terminology document from 2 separately proposed work items for benchmarking sub-IP layer protection mechanisms draft-poretsky-mpls-protection-meth-04.txt, Benchmarking Methodology for MPLS Protection Mechanisms – Submitted with updated terminology to match new Terminology doc – Prior revisions were reviewed by participants in MPLS WG and BMWG – Fast Reroute mechanism now RFC 4090 6 NETWORK PROTECTION MECHANISMS (Proposed WG Work Item) (2 of 2) • Need for this work item: 1. The IP network layer provides route convergence to protect data traffic against planned and unplanned failures in the internet. • BWMG has work items to address convergence benchmarking. 2. Technologies that function at sub-IP layers can be enabled to provide further protection of IP traffic. 3. The metrics for benchmarking the performance of sub-IP protection mechanisms can be measured at the IP layer, so that the results are always measured in reference to IP and independent of the specific protection mechanism being used. • • Enables different protection mechanisms to be benchmarked and compared Enables different implementations of the same protection mechanism to be benchmarked and compared 4. Sub-IP protection mechanisms include High Availability (HA) stateful failover. Virtual Router Redundancy Protocol (VRRP), Automatic Protection Switching (APS) for SONET/SDH, and Fast Reroute for Multi-Protocol Label Switching (MPLS). 5. It is intended that there can exist unique methodology documents for each sub-IP protection mechanism, such as MPLS. 7
